ModularInjection

使用autofac实现模块化注入

Nuget

1.package address https://www.nuget.org/packages/Autofac.ModularInjection.DependencyInjection/

使用方式

1.创建.net core2.2或 3.0+项目，

2.添加初始化模块类，此类需继承DiModule，如 public class StartupDiModule: ModularInjection.DiModule，若想实现跨类库注入, 请在初始化模块类添加此特性 [DependsOn(typeof(模块化类))]

core2.2项目代码演示

1.在Startup类中添加如下代码片段

  public IServiceProvider ConfigureServices(IServiceCollection services)
      {
          services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
          return  services.AddModule<StartupDiModule>();
      }

core3.0+项目代码演示

1. 在Program类中添加 .UseServiceProviderFactory(new AutofacServiceProviderFactory<初始化模块的类>())

   public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseServiceProviderFactory(new AutofacServiceProviderFactory<StartupDiModule>())
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
   

2.在Startup类中添加如下代码片段

  public void ConfigureContainer(ContainerBuilder builder)
      {
         //自定义注入
      }

core2.2或3.0+项目添加初始化模块类

添加初始化模块类

[DependsOn(typeof(模块化类))]
public class StartupDiModule: ModularInjection.DiModule
{
    public override void PreInitialize()
    {
        //预初始化
    }

    public override void Initialize()
    {
        //初始化
    }

    public override void PostInitialize()
    {
        //后初始化
    }
}
